26 Claims.

This invention relates to web supply mechanism for machines, such as, printing'machines that operate on webs fed from web rolls, and has particular application to high speed rotary printing machines that are used for printing newspapers and similar products. Patent No. 2,155,430 was granted April 25, 1939, on an application of which this is a division.

It is desirable in press operation to replace the web of an expiring roll after the web of a replacement roll has been joined thereto, the operation of said severing means being coordinated with thejoining-of the webs, whereby the web will be severed a definite distance back of the point where the join is made, which distance will be substantially the same at every operating speed.

Another object is to provide an improved severing means which will be actuated by means of a lug rotatable with the web replacement roll and a latch releasable thereby to actuate a cutter blade and cause same to sever theweb of the expiring web roll after a join is made with the instead of being automatically controlled, certain movements are manually controlled. The speed of operation, however, is not retarded by the partial manual control.

Improved means are also provided for controlling the rotation of the roll during acceleration and deceleration of the machine.

Among the objects of this invention, one is to provide a web supply mechanism for machines that run at high speed while operating upon a web of material, in which the web fed from an exhausting w'eb roll may be replaced with web from a replacement roll without reducing'the speed of the machine.

Another object is to provide a web supply mechanism in which the web from a replacement roll is joined to the web of a running roll, ,in which the means for making the join is man-. ually movable to a pre-pasting position.

Another object is to provide a web supply mechanism having a 'web deflector adapted to press a running web against an adhesive portion on the web end of a replacement roll, the said deflector being manually movable into a pre-' pasting position and power actuated upon the energization of an electrical circuit.

'Another object is to provide a web supply mechanism having a web deflector manually movable to an operating position and an electrically controlled timing means for timing the replacement roll.

With the foregoing and other objects in view,

which will appear in the following description,

the invention resides in the combination and the web of the replacement roll is about to be joined to the web of the running roll, the latter having been reduced to about the point of exhaustion;

The pulley 35 is mounted on a shaft 38. journalled in bearings 39, whichbearings are secured to the side members 25, a of the machine base frame. A suitable drive is provided for the shaft 38 through gearing indicated at 4| and a sprocket and chain connection 42, which are preferably driven from a driving source in the machine, such as, indicated by the shaft 40. Said gearing 4! is timed to maintain the running speed of the belt at a speed which is slightly slower than that of the running web so as to provide a constant braking action on the web roll, which is varied according to the amount of wrap provided by the belt around the web roll and by" the belt tension.

switches employed'in the control of the web roll web guide rollers 25, while. above same, the usual printing-mechanism not included in this invention is mounted.

A reel 21 is rotatably mounted upon a shaft 28 which shaft is carried by pedestals 29, the upper ends of same being shown in Figure 2. A motor drive means indicated at M of the wiring diagram is connected in driving relation with the shaft 28 and is energized periodically by'pressing one of two buttons 3M, 3) to'energize the motor circuit and cause the motor M to rotate the said reel. Web rolls 32 are supported on arms 33, projecting outwardly from the reel 21,in any conventional manner. 32a is shown mounted on the reel in an uppermost position and has the web 'W feeding therefrom over the guide rollers 26 which will be referred to hereinafter as the running web roll. In Figure 2, another web roll 32b is shown as V having taken the place of'the' aforementioned running web roll 32a, and will be referredto hereinafter as the replacement roll.

In Figure 1, one web roll.

The pulley 36 is rotatably mounted on a shaft 43 journalled in bearings 44 which are also secured to the base frame members 25 and 25a, said shaft 43 also having arms 45 fixed thereto (Figure 5), positioned at either side of the 'pulley 35. A short shaft 46 is rotatably mounted between the projecting ends 41 of said arms 45 and has secured thereto a pair of downwardly projecting pivotal arms 48, between which a pulley 31 is rotatably mounted on a shaft 49. One -of said pivotal arms has an upwardly projecting end 5| which has a coil spring connected thereto, the other end of which spring is attached to a stationary cross bar 53 secured between the arms 45, and is adapted to rock the pivotal arm 38 outward to cause the pulley 31 to apply a tension on the endless belt 34.

While the above described endless belt mounting is described in the singular, it is to beunderstood that more than one mounting may be used. In the particular structure of this invention two belt mountings are provided at substantially the same distance from each side of the base frame members 25, 25a, in the same relation as'that indicated in Figure 5, which shows the location in relation to the one side member 25a. 7

A motor 54, shown in detail inFigures 16 and 17 is mounted on the side member: 25a, which motor is provided with axmagnetic brake generally indicated at 55 and a reduction gearing 56.

- When said motor is energized, ina manner to be hereinafter described, the gear segment Will'be partially rotated in a.;clock wise or counter-clock- V wise direction and thereby rock the shaft 43 and The normal running position for the running web roll is the uppermost position as shown in Figure 1, but after the roll has beenreduced to a certain predetermined diameter, an attendant will energize the motor circuit to rotate the reel I in a counter-clockwise direction by pressing the push button 31a, whereby the reel willbe rotated to move a replacement roll into the-upper position to be joined with the web running from the expiring roll, which latter roll will have been moved downward tothe position shown inFigcreasing a, braking pressure which is constantly applied to the running web roll.

Said mechanism comprises one or more endless belts 34, guided over pulleys 35, 36 having the arms 45 in the same direction. In so doing; I the wrap of the belt upon the running web roll is-increased or decreasedin varying degree in response to: variation in web tension and the braking pressure of same is varied accordingly.

It will be observed that by mounting the mov- I "able pulley in the manner described, it is possible to use a short swinging bracket for the movable pulley which is light inwe'ight and does not require much space for movement. It will also be observed that the tension of the spring 52 will increase as the wrap of the beltis increased and thus further increase the braking action of the belt.

' The energization of themotor 54 is controlled by the movement of a. floating web roller 59, which roller is mounted so as to engage the running web and change its position'wh'en the web tension is increased or decreased. The mounting forthe floating roller comprises arms GI and 62 which carry the said roller 59 at one end thereof and which have their opposite ends mounted on a shaft 63, said shaft being supported in bearings 64' secured to the side base frame members 26-2511.

A weight carrying arm 65 is mounted at one end of the shaft 63 as shown in Figures 1 and 2,

- and is adapted to support a weight 66 which is- 18--I4 extending downwardly therefrom and each arm has a roller -16 at the end thereof, positioned directly in the path of the cam shoe 68. Each switch is in a normally open position and is electrically connected with the motor 58 in such manner, that when either one of the switch arms H8, is is rocked, a circuit will be completed which will drive the motor 58 in a clockwise or counter-clockwise direction, to thus vary the braking action of the endless belt 38 upon the running web roll, as previously described, and thereby return the web to its normal running tension. The said rocking action of the switch arms is caused by the rocking movement of the cam shoe 69, through the movement of thefloating roller 58, as the position of the roller or decreased tension on the running web as it is drawn from the roll.

A uniform running tension on the web running to the machine is thus automatically maintained by means of the above described mechanism and is directly controlled by the movement or change in position of the floating web guide roller.

Having described the mechanism for controlling the tension of the running 'web, the mechanism for joining the web of an expiring web roll with that of a replacement roll and themeans for severing the web of the expiring roll after a join is made, will now bedescribed.

Referring to Figures 1 to 4. a twin frame structure indicated generally by the reference character 8i comprises a web deflector frame 82 carried by a shaft 88 and a cutter supporting frame 83 carried by a sleeve 85 both of which frames are movable about the same axial center. Said shaft 88 passes through the sleeve 85, which sleeve is journalled in bearings 86 forming parts oftwo brackets 87, depending from and secured to the base frame members -251 The twin frame structure is best shownin Figure 3 in which the mechanism located at one end and center of said frame structure are shown; it being understood that the mechanism on the opposite end will be a duplicate.

The web deflecting frame structure generally comprises two end arms 98 flxedon the outer ends of the shaft 84, which project beyond the ends of the sleeve 85, and have a beam 88 secured to the outer portions of the projecting ends thereof.

Brushes 89 are mounted upon said beam which project outward and are adapted to be brought into engagement with the surface of the running web previous to making a join between the web of-the expiring web roll and the web of the replacement roll, in such manner as will be hereinafter described.

The cutter supporting frame comprises two outer arms 8| and a centrally disposed arm Ola which are keyed to the sleeve 86, with the outer arms positioned adjacent to the web deflecting changes, said change being due to an increased frame arms 88, and have a cutter supporting sheath 82 secured at the lower ends thereof as shown in Figures 9 to 11, between which a cutter 83 is slidably mounted. A handle 84 is secured to one arm 8| as shown in Figure 3.

The web deflecting frame and cutter supporting frame are normally joined together by means of a latch shown in Figure '7; which comprises a hook 95 adjustably secured to the web deflector frame beam 88, and a pin 96 secured at one end of a rocking lever 91, which lever forms part of a latch releasing mechanism assembled within a housing 98, on the arm 8Ia, and which will be hereinafter described. v

It will be observed that since the twin frame members are latched together, they will thus move in unison when moved from a non-operating position as shown in Figure l to an operating o'r pre-joining position as shown in Figure 2. A heavy counterbalancing spring 88 is mounted over the sleeve 86, and has one end secured to a portion of the bearing 88 and the other end secured to a collar I8I keyed to the sleeve 85 as clearly indicated in Figure 3. The spring action is such that the tension upon same is increased when the frames are lowered, thereby retarding action of which spring provides the power means for actuating the web deflector preparatory to making a join between the web of the expiring web roll and the web of the replacement roll. Said spring I82 also provides additional means to hold the frame structure in a raised position due to its movement off center as shown clearly in Figure 1. u

A'shaft- I88, (Figure 3) is .rotatably mounted in bearings I85-I85a on the cutterframe arms 8| and 8I a respectively and has secured thereto a dog I86. A counterbalancing spring I8? is mounted over said shaft and has one end in engagementwith the dog I86 and the other end in engagement with the bearing I and is tensioned so as to hold the end I88 of the dog against the peripheral surface of one of the bearing members 86 on the bracket 81. Two lugs I88--I I8 are provided on the periphery of said bearing member 86 in the path of the end I88 of the dog 588 and are adapted to be engaged by said dog when the twin frame structure is in a lowered position as indicated in Figure 4 or when in a raised position. A handle I is secured to the rod H88 to provide a means for manually releasing the dog I86 from the lug II8 when it is desired to swing the twin frame structure upward. When the twin frame structure is in araised position, as in Figure -1 the end of the dog will engage the upper lug 19 which lug will function as a stop to prevent any further movement upward by the action of the tension spring I82 and when said twin frame structure is in a lowered position, the end ofthe dog will engage the lower lug H8 and thereby cause the brush portion 89 of the web deflector frame and the sheath 92 of the cutter frame to be set in a flxedposition'with relation to the running web of the expiring web roll.

The pulling power of the tension spring I82 becomes effective at the instant the latch pin 86 is released. from the hook 85, which release separates the web deflector frame from the cutter frame and allows the web deflector frame in be pulled forward, while the cutter frame remains stationary.

The action of the latch releasing mechanism will now be described.

Referring to Figures 7 and 8, the aforesaid rocking lever 91 is mounted on a stud II2 projecting from a boss II3 within the housing 98, and is held thereon by means of a washer and pin indicated at H4. The lever is adapted to be rocked about said stud II2 by means of the action of a solenoid magnet II5. Said solenoid has a plunger H6, and a link II'I connecting same with a bifurcated end of the lever 91. When ment web roll rotates, the time between the depression of the button I29 and the action of the latch releasing solenoid. H5, is almost instanenergized, the plunger will be drawn into the solenoid and the lever 91 will be rocked about the stud H2, which movement will release, the pin 96 from the hook 95 and thereby allow the web deflector frame to be pulled forward by the spring I02 to a web joining position shown in Figure 21. A stop H8 is provided on the plunger IIG to limit the inward movement of same and an adjustable stop screw H9 is provided within one wall of the housing 98 to limit the downward movement of the lever. A spring I2I tensioned between one end of the latch pin 96 and an ear I22 on one wall of the housing 98 is provided to hold the pin 98 in normal engagement with the hook 95.

Before said latch releasing solenoid is energized however, a timing means which rotates web of the replacement roll in engagement withthe body portion thereof, as indicated at, I23 and has a cam member I26 thereon which is rotatable with the replacement roll. A switch arm I21, on a circuit closing switch I28, is nortaneous.

The energization of the solenoid I I5 will therefore release the web deflector frame, to allow it to be pulled forward by the tension of the springs I02 and cause the brushes 89 to force the expiring web against the surface of the replacement web roll as shown in Figure 21, and when the adhesive portion on said surface reaches a position opposite the brushes 89 the Web end of said roll will adhere to the web of the expiring web roll and any holding means will be automatically released.

Immediately after the join is made, the cutter mechanism is actuated to sever the expiring web by the action of a lug I58 on the upper end of the replacement roll web holding mechanism mally positioned in the path of the cam I28,

and is moved to close said switch I28 upon each rotation of said cam but is ineffective until a push button I29 on the arm 33, supporti g the replacement roll, is depressed.

An adhesive may be provided on the outer surface of the end of the web replacement roll in any suitable manner for'the running web of an expiring web roll to be brushed against by the brush portion 89 of the web deflecting frame 82 at the time a join is made. One method of preparing the adhesive portion of a replacement roll for a web joining operation is disclosed in a copending application, Serial Number 578,270, now Patent No, 1,995,269, dated March 19, 1935.

When the expiring web roll is reduced to a diameter of almost complete exhaustion, as shown in Figure 2, the push button I 29 on the replacement roll arm is pressed by the attendant and at the instant thereafter that the cam- I23, (Figure 2), in a manner to be hereinafter described. The said cutter mechanism, best shown in Figures 3 and 4 and Figures 9 to 15, comprises a cutter blade 93 slidably mounted between the upper and lower plates I30, I3I of the sheath 92. Guide studs I32 pass through the upper and lower sheath plates and through angularly disposed guide slots I33 in the cuttr blade 93. A spring I34, tensioned between one end I35 of the cutter blade 93 and a pin I33a between the sheath'plates I30, I3I and positioned within a recess I38 in said sheath, is adapted to pull the cutter blade from a normally inoperative or locked position as shown in Figure 9, to a cutting position as shown in Figure 10. A resetting handle I3'I is secured to the cutter blade and comprises twoposts I38 and I39 which project through clearance openings I, III in the sheath plates and are joined together as shown in Figure 15.

Ameans is provided for locking the said cutter blade in its retracted position, which comprises a rocking arm I42 secured to a rock shaft I43, and has a pin I44 secured at the outerend thereof, which is adapted to engage an opening I45 in the cutter blade '93 and thereby provide a latch for said cutter blade when retracted. (See Figure 13). The said rock shaft I43 is mounted in bearings I48 provided at the lower ends of the cutter frame arms 9I-9Ia. A coil spring I41 mounted over the shaft I43 (see Figure 9) has one end secured to one end of a bearing I48 and the other end secured to a collar I48 fixed to the shaft I43 and is tensioned so as to normally hold the latch pin I44 on the arm I42 in engagement with the opening I45 in the cutter blade 93. A rocking lever I49 is also secured to one end of the shaft I43.

A shaft I5I is supported by bearings I52 secured to the lower surface of the web deflector frame beam 88, as shown in Figures ,3 and 4, and has mounted thereon a lever I53 which lever is joined to the above rocking lever I49 by means of a link I54.

The front of 'said lever I53 is shown as spaced ashort distance away from the bottom of the beam 88, which distance is increased when the web deflector moves forward to the web Joining position. The lug I58, previously referred to as on the upper end of the web holding mechanism I23, rotates with the web roll 32b and is adapted to strike the lower free end of the lever I53 and rock same about the shaft I5I. This movement will cause the link I54 to move upward and the rocking lever I49 to be rocked in a counterclockwise direction. The arm I42 will thus be rocked roll below the join. It is to be particularly noted that the web of the expiring web roll'will be stretched tightly across the ends of the upper and lower sheath plates I30 and I3I, when the cutter frame is lowered to a web pre-cutting position, as is clearly shown in Figures 2 and 4. Therefore, the taut condition of the web at this point at the end of the. sheath plates will cause the teeth of the cutter blade to easily penetrate the web and sever same.

At the time'a join is being made, it is desirable to break the circuit to the motor 54 to prevent same from varying the pressure of the belt 34 upon the replacement web roll 32b. A circuit controlling mechanism is therefore provided which comprises a switch I55 secured to the bracket 81 and has a switch actuating arm I56 mounted thereon. A cam plate I51 shown in Figures 3, 4 and 6, is secured to the tension spring lever I03 on the web deflecting frame shaft 84 and is adapted to be rocked when the twin frame structure ismoved to and from a web joining position. Referring to Figure 6,'the switch actuating arm I56 is shown as moved to a motor circuit breaking position by the camplate I51, which position agrees with the lowered position of the'twin tension. At I14 a relay is shown for energizing the magnetic brake 55 and to provide a normally closed contact 205 when deenergized; I15 and I16 indicate relays foractuating the motor 54 in a direction to decrease or increase the belt tension respectively; I11 is a relay which is energized by the upper push button 3Ia in the mounting 3I to drive the reel 21 in a forward or counter-clockwise direction, and I18 is a similar relay which is actuated by the lower push button 3Ib to reverse the direction of the reel 21.

The position of the parts shown in indicate a normal operating position with the main motor driving, and agree with the positions shown in Figures 1 and 18, wherein the web W is being drawn from the running web roll 32a and the web joining and cutting mechanism are in a raised or non-operative position.

While the mechanism is running normally with the web feeding at the desired tension, the motor 54 is idle and the magnetic brake circuit is deenergized, thus causing the motor brake 55 to hold and thereby maintain the arm in a fixed position.

As soon as the tension of the running web varies, it immediately causes a change in position of the floating roller 59 and rocks the cam shoe 69 to the right or to the left to close one of the two switches H or 12. 'If the tension of the running web is more than the desired tension, the said cam shoe 69 will rock to the left and cause the contacts onthe switch H to be closed.

frame structure shown in Figure 4. Immediately,

after the web deflector frame is released to join the web, the cam plate I51 will pass beyond the switch actuating arm I56 and said arm I will drop to its normal vertical position indicated in dotted lines. On the return movement of the cam plate I51, i. e., when the twin frame structure is raised, the switch actuating arm will be kicked upward without effecting the switch, then will drop back to its normal vertical position.

A limit switch is also provided at I59, Figures 2 and 5, and has an operating arm I6I with a roller I62-at the end thereof, which roller extends in the path of a lug I63 on the hub of .the gear segment 58. If the arms 45 are raised beyond a certain predetermined limit the lug I63 will strike the roller I62 and break the circuit to the motor 54 to make same inoperative for the less tension movements of the arms 45.

The various limit switches, operating motors,

etc. heretofore referred to and other solenoids,

relays and the like are indicated diagrammatically in the wiring diagram illustrated in Figure 22 including all ofthe circuits therefor, all of which cooperate in the complete operation of the relay indicated at I13 which is energized only' when the press drive is operating at web threading speed. The purpose of the latter relay is to open the circuit to the switch 12 by breaking the circuit on the contacts 224 and to close the 'circuit to the switch H by bridging the contacts 224, whereby the motor 54 is permitted to operate for less tension, but is inoperative for more When said contacts are closed, a circuit is completed to the motor 54 which is traced from the line L2 through conductor 203, normally closed contacts I59, conductor 202, relay coil I15, conductor 20I and the closed switch 1|, then through the conductor 204, normally closed contacts 205, conductor 206, closed contacts 201, conductor 208, closed contacts 209, conductor 2I0, closed contacts 2 and conductor 2I2 to the line LI. The relay I15 is thus energized which closes three sets of contacts 2I3, 2 and 220 which energize the motor 54, and the circuit to the brake 55. The circuit to energize, the motor is a conventional three phase circuit from line LI, L2 and L3, and may be traced as follows:

From LI through conductors 249 and 250 through contactor 220, conductor 214 to motor conductor 2I5, contactor 2I3, conductor 2I8 to motor 54. The motor 541s thereby driven in a direction which will reduce the braking pressure of the belt 34 upon the running web roll until the floating web roller 59 returns to its normal running position, whereupon the circuit is again broken.

When the tension of the running web is less than the desired tension, the floating roller will drop and the cam shoe 69 will rock to close the switch 12 and thereby cause a circuit to be closed which will drive the motor 54 in a reverse direction to provide a greater braking pressure upon the running web roll through the belt 34. Said latter circuit is traced from the line L2 through the conductor 2I6, relay coil I15 and conductor 22I then through a conductor 222, switch 12 and a conductor 223, then through a normally closed contact 224, which is adapted to be opened by the action of the threader relay.

the diagram motor 54.

' 251, conductor 254, electro-magnetic brake 55,

The relay coil H6 is I drive of the motor 54 to increase the braking tension of the belt 34 on the running web roll 32a,

- and may be traced as follows: LI through conductors 249, 2285, contact 240, conductor 214, to From L2 through conductors M6, 221, contact 225, conductor 2I8 to motor 54. From L3 through conductors 2I5, 228, contact 226, conductor 2H to motor 54.

When the running web roll 32a is reduced in size to about the proportionate size shown in Figure 19, the attendant will press the upper button em in the push button box 3I to close a circuit to the reel driving motor M, which will drive the said reel in a counter-clockwise direction to move the running web roll 32a and. a replacement roll 32b tothe relative positions shown in Figure 20 and Figure 2. The circuit com pleted by pressing the said upper button is traced from the line L2, through conductor 23I, relay coil I11, conductor 232, push button 3Ia, conductors 233, 234 and 2I2 to the line LI. A similar circuit, which is energized when the lower push button 3Ib is pushed to reverse the direction of the reel, is traced from the line L2 through the conductors 23I and 244, 245, relay coil I18, conductor 235, push button 3Ib, conductors 233, 234 and 2I2 to the line LI.

The energization of either of the above mentioned push buttons 3Ia or 3Ib will thus energize one of the coils I11 or I18, whereby contacts are made to complete a circuit to the motor M to drive same in a forward or reverse direction and to energize the circuit to the brake magnet. in motor 55 and also to break the circuit to switches H or 12 in order to make the motor circuit inoperative while the reel is moving. The circuit to energize the motor M is also a conventional three phase circuit from line LI, L2 and L3. The circuit to the motor M while turning the reel in a counter-clockwise direction may be traced as follows: from L2 through conductor 23I, contact 236, conductors 231, 238 to motor M. From L3 through conductor 243, contact 242, conductors 24I and 230, to motor M. From LI through conductor 2 I2, conductor 234 to motor M. The circult to the motor while the reel is being rotated in a clockwise direction may be traced as follows:

from L2 conductors 23I, 244 and 245, contact 246, conductor 239 to motor M. From L3 through conductor 243, 248, contact 241, conductor 238 to motor M. From LI through conductors 2I2,- and conductor 234 to motor M. At thesame time, one of the normally closed contactor 209 or 2 is opened by either of the energized relay coils I11 or I18, to open the circuit to the switches II and 12 thereby making them inoperative regardless of the position of the cam shoe 69. Also,

at this time, a circuit is completed through the magnetic brake to energize same which is traced for the contacts of relay I11 from the line LI,

- for the contacts of the relay I18 from the line LI, through conductors 2'2 and 256, contacts conductors 255 and 23}, to the line L2.

The replacement web roll 321) having taken the position previously occupied by the running roll 3211, as in Figures 2 and 20, the attendant next swings-the twin frame structure 8i downward to the position also shown in Figures 2 and 20 and is then ready to join the running web to the web of the replacement roll, the speed of the latter having been accelerated to substantially the same speed as the running web by engagement of the roll with the belts 34.

When the running web roll has been reduced to a predetermined size, the attendant will press the push button I29 on the arm 33 which supports the replacement roll, which will cause the web deflector and brush portion to be drawn forward after the switch I28 is closed, to effect a join between the running web and the web replacement roll and after said join is completed the running web is cut below the join as previously described.

The parts which are electrically operated when the push button I29 is pressed are traced through the circuit as follows:

From the line LI the circuit is completed through conductors 2I2, 234, 260 and 26I, one brush 262 and slip ring 263, conductor 210, switch contactor I21, conductor I28, push button I29, conductor 21I, then through slip ring 265, brush 264, a conductor 266 and relay coil I19, then through conductors 261, 268, 244 and 23I to the line L2. The slip rings 263 and 265 are suitably mountedover'the reel shaft 28 to rotate with thev reel 21 and the brushes 262 and 264 are suitably mounted so as to remain in contact with I a the said slip rings.

When the push button I29 is pressed the circuit will. not be completed until the switch I21 is closed by the cam I26, which cam and pushwbutton are connected in series with the conductors 210 and HI, which conductors are secured to the slip rings 265 and 263 respectively. A completed circuit through the above will thus energize the relay solenoid I19 and cause a circuit to be completed to thev latch releasing solenoid I I 5 to release the web deflector frame 82 as aforedescribed. The circuit through the said solenoid H5 is completed from the line L2 through conductors 23I, 244, 268, contacts 212, conductor 213 through solenoid II5, then through conductors 260, 234, and 2I2 to the line LI.

, During the last part of the period that the twin frame, structure 8i is swung downward and until the web join is made, the circuits to the motor 54 are broken and the motor brake circuit is energized. These conditions are the result of the engagement of the cam plate I51 with the switch actuating arm I56 of the switch I55, which cam plate is movable with the shaft 84 that supports the web deflector frame 82. .When

the above condition occurs, a circuit is completed to energize the relay solenoid I14, which will open the normally closed contacts 205 thereby making the motor '54 inoperative, and is traced fromthe line L2 through conductor 203, relay' coil I14, conductor 280, closed contacts on switch I55, conductor 20I, conductor 206, contacts 201, conductor 208, contacts 209, conductor 2I0, contacts 2II, conductor 2I2 to line LI. The relay coil I14, having thus' been energized, will open the normally closed contacts 205 which will open the circuit between the motor 54 and the cam actuated switches H and 12, to prevent any movement of the floating web roller from ener- -the arm I56 to permit same to drop and cause the switch I55 to open, thereby returning the complete circuit to its normal running condition.

In addition to the functions previously described, provisi-on is made for applying additional braking action to the web roll when the press is decelerated rapidly. Controllers for newspaper presses are generally provided with an emergency stopping button, which in addition to breakingthe circuit to the motor is usually arranged to apply brakes to the motor and to the printing cylinders. In Figure 22 relay I'll is indicated and it is intended that this be connected in circuit so as to be operated by the emergency stop push button. Thus when-the machine is stopped quickly this relay is energized, closing contacts 286 which completes a circ'w'iu"that may be traced from Ll through conductor 249, contacts 286, conductor HI, and relay I16 to L2. The motor 54 is thereby energized in the same manner as mechanism, and means to trip the cutter latching mechanism, whereby a join is made between the running web and the web end of the re placement roll, and the running web is severed immediately thereafter.

whereby the deflecting mechanism is pulled forward to move the running webv into engagement with an adhesive portion on the web end of the replacement roll, a sheath on the end of the cutting mechanism having a protractable cutter blade within same, a latch to maintain said outter blade ina retracted position, and means to release said latch after the web join is made to actuate the cutter and sever the running web below-the join.

when operated to increase tension on the web;

and the increased bra-king'pressure on the roll is maintained until the relay I'll is deenergized on the stopping of the press driving motor.

It is to be understood that while the foregoing description of the electrical circuits relates to the use of alternating current as the power source that direct current may be used, if desired, and that any alterations in the wiring which are required for the change of current can readily be made by those familiar with this art. I

It will be observed from the foregoing that a simplified form of web supply mechanism and means for controlling same has been provided which is positive in operation and permits a web 3.
